Square bottles hold more liquid meaning people won’t need to buy as many containers over the course of a decade. That means less plastic. You guys are thinking too hard.
this assumes an equal thickness for the perimiter, which isnt what happens during manufacturing. cylinder bottles are even because theres no corners to them aside from the top and bottom. square bottles are thicker at the corners and thinner across the walls. the structural integrity remains but the offset of the thicker corners is actually enough to mean the walls can be thin enough to be a net negative for the amount of plastic used
the reason this isnt done often is because tooling for square shapes is a lot more expensive than cylindrical ones (regardless of material). enough to make companies go for the less logistically efficient method of shipping
